When you you are going to do something relevant to mechanism, the preparation is very important. It is very essential that you spend time preparing so that everything lines up.

Leaking toilets can also be very smelly and shameful. Finding out how to fix the problem as soon as possible will save you a lot of embarrassment.

Place newspapers or towels on the ground adjacent to the bathroom. The toilet will be placed on these after you disconnect it from the flange.

Step 3: Remove the toilet

Before you can set up a new toilet flange, firstly, you must remove the toilet, which is sealed into the existing one. Now comes the somewhat difficult part. A toilet can weigh upwards of 120 pounds. It’s always best if you can enlist the aid of a family member, friend or extremely nice neighbor. Before lifting, rock it back and forth a few times to break the wax seal. Undo the 2 bolts holding the toilet down to the floor using your adjustable wrench and then move the toilet out of the way. It might take a bit of rocking before the toilet will come away from the wall. The wax seal is designed to stop gasses from escaping the waste pipe. When lifting, be sure to use your legs, not your back. Lift it straight up and carefully set it on top of the newspapers or towels that you already placed on the floor.

Step 4: Remove the old flange.

By using a putty knife, it will be much more easy to clean the wax from the flange. Remove the screws attaching it to the floor using your multi-head screwdriver. Keep the screws for later. Remove the flange and clean it off either in the sink or with a disinfecting wipe. Tuck an old rag into the sewage outflow pipe to block any unwanted sewer smells or gasses.

Measure the diameter of the sewer pipe to determine the correct size for the flange. Then, place your old one in a bag and head to a nearest home improvement store, a hardware store or a plumbing supply store and purchase a flange of the same size and shape.

Step 5: Installing the new flange

Make sure the flange you purchase is the same size and shape. In addition to the flange, you will need a new wax ring. Purchase a new wax ring at the store along with your new flange. The correct nuts and bolts often come with the toilet flange. If for any reason these pieces are not included, you will have the ones you saved during removal. If they were in bad shape, you will need to purchase new nuts and bolts. The new bolts will secure the flange against the bottom of the toilet.

Screw the new flange to the floor using a screwdriver and the new screws that came in the product package. Make sure that there are no spaces between the flange and the floor before screwing it into place. Attach using your used or new screws and bolts. Once in place, you should have two bolts sticking up for the toilet.

Lift up the toilet and push the new wax ring into place on the bottom. Now it’s just time to fit the toilet, the screws will be tightened so that the toilet is sturdy and doesn’t rock. The seal should be checked to ensure that it is watertight. Place the toilet on top of the flange, lining up the toilet with the new bolts. Press down tightly to seal the wax ring. Replace the nuts that hold the toilet onto the flange. Hand-tighten them before using a wrench to tightly secure them.
